Silent Thrombotic Thrombocytopenic Purpura: PLASMIC, Lessons Learned, and Current Management Overview.

Thrombotic thrombocytopenic purpura (TTP) is a rare, life-threatening autoimmune or hereditary thrombotic microangiopathy (TMA) that may be difficult to recognize given the wide spectrum of presenting symptoms. The clinical diagnosis of TTP is based on thrombocytopenia, microangiopathic hemolytic anemia and is confirmed by a disintegrin-like and metalloproteinase with thrombospondin type one motif, member 13 (ADAMTS13) <10%. However, the latter confirmation is not rapidly available, and treatment is typically initiated based on the degree of clinical suspicion.
